50确定含金矿 石工艺流程时要注意什么?
    含金矿石选别工艺流程取决于矿石中的金和其他有价组分的赋存状态和嵌布特性，以及矿床的储量规模和建厂条件。
    任何一种含金矿石都各有其特性，即使同一矿床，深部和浅部的矿石性质也有差异，因此选别方法也会不同，合理的工艺流程必须经过小型试验或扩大试验才能确定。
    确定选别工艺流程时，应注意以下几点。

(1) 提前回收大粒金

对含有大粒金(>0. 1mm)的含金矿石，应设重选或混汞作业尽早回收，以免这部分金在选别过程中流失和分散积存在设备及管路中。
(2)泥砂分选
    当矿石中含有含金矿泥或几乎不含金的矿泥时，为了有效地回收金，可根据矿泥和矿砂不同的含金特点分别进行浮选、重选和氰化，可以提高金的回收率，并增大处理量。
(3)阶段磨矿阶段选别
    矿石中的金呈粗细不均匀状态嵌布时，可采用阶段磨矿阶段选别工艺提高金的回收率。
(4) 采用选冶(水冶)联合流程
    由于金在矿石中的赋存状态和嵌布粒度不同，与金共生的金属矿物含量各异，采用单独一种选矿 方法往往回收率较低，有价元素也得不到合理的利用，除少数矿石仅采用一种选矿方法即可获得较高的金回收率外，绝大多数矿石必须用选冶联合流程，才能获得较高的金回收率,

Flotation process of precious metal ore with pwdl multi suction sewage pump

What should be paid attention to when determining the technological process of gold ore?

The beneficiation process of gold bearing ore depends on the occurrence and dissemination characteristics of gold and other valuable components in the ore, as well as the reserve scale and plant construction conditions of the deposit.

Any kind of gold bearing ore has its own characteristics. Even for the same deposit, the deep and shallow ore properties are also different, so the separation method will be different. The reasonable technological process must be determined by small-scale test or extended test.

Attention should be paid to the following points when determining the beneficiation process flow.

(1) Recovery of large grains of gold in advance

For gold ore containing large grains of gold (> 0.1 mm), gravity separation or mercury mixing operation should be set up to recover as soon as possible, so as to avoid the loss and dispersion of this part of gold in the separation process and deposit in the equipment and pipeline.

(2) Mud sand separation

In order to effectively recover gold, flotation, gravity separation and cyanidation can be carried out according to the different gold bearing characteristics of slime and ore, which can improve the recovery rate of gold and increase the treatment capacity.

(3) Stage grinding and stage separation

When the gold in the ore is unevenly distributed, the stage grinding and stage separation process can be used to improve the recovery rate of gold.

(4) Combined process of beneficiation and Metallurgy (hydrometallurgy) is adopted

Due to the different occurrence and distribution of gold in the ore, the content of metal minerals associated with gold is different, so a single mineral processing method is adopted The recovery rate of the method is usually low and the valuable elements can not be reasonably utilized. Except for a few ores which can obtain high gold recovery by only one mineral processing method, the vast majority of ores must use the combined process of dressing and metallurgy to obtain high gold recovery,
